Section 3: Bony Structures Of The Spine And Supporting Soft Tissue Flashcards
Describes the front and back halves of the entire body
Frontal or coronal plane
Describe the median or Sagittal plane of the body
The left and right sides of the entire body
Describe the transverse or axial plane
Divides the body at the waist (top and bottom halves of the body)
How many distinctive curves does the mature spine have?
4
A convex curve in the spine (convexity towards the back of the spine) is what type of curve?
Kyphotic
A concave curve in the spine(concavity towards the back of the spine) and is found in the cervical and lumbar levels of the spine is what type of curve?
Lordotic
What are the three main functions of the spine?
- Protect the spinal cord, nerve roots, and several of the body’s organs
- Provide structural support and balance for upright posture
- Enable flexible motion
Which region of the spine has 7 vertebrae, and its first and second vertebrae are named atlas and axis respectively?
Cervical spine
The atlas does not have a (blank blank), but does have a thick (blank blank) and a thin (blank blank).
Vertebral body
Anterior arch
Posterior arch
This is the bony knob that sits on the axis and sticks up through the hole of the atlas that allows the head to turn from side to side.
The odontoid process
This spine has 12 vertebrae, has a longer spinous process, and has a pair of attached ribs on each.
Thoracic Spine
This spine has 5 vertebrae and is designed to carry the body’s weight. It’s normal curvature is lordotic.
Lumbar Spine
This part of the spine is located behind the pelvis and has its 5 vertebrae infused together
The sacrum
Slow the sacrum you will find this - comprised of 5 bones fused together.
Coccyx (tailbone)
Name the 3 ligaments of the spine
Ligamentum Flavum (Inside)
Inter-spinous Ligament (in between)
Supra- spinous Ligament (outside)
